International Classification:

B41J023/00

US Classification:

347/037000, 347/019000

Abstract:

A method of positioning an ink jet printhead in a printer includes dividing a bitmap into a plurality of rows of tiles. A subset of the rows of tiles to be printed in a next pass of the printhead is identified. Printable ones of the tiles in the subset of rows are identified. The printable tiles contain printable data. Within each printable tile, a top most location of the printable data and at least one of a left most location of the printable data and a right most location of the printable data are identified. A print medium is advanced in a feed direction until a portion of the print medium corresponding with the top most location of the printable data of at least one printable tile is substantially aligned with a top nozzle of the printhead. The printhead is moved, in a scan direction, directly to a position on the print medium corresponding to one of the left most location of the printable data of at least one printable tile and the right most location of the printable data of at least one printable tile.

International Classification:

G06K001/00

US Classification:

358001150

Abstract:

A method of printing includes the steps of: receiving an image data file from an originator at said printer, said image data file including at least one origination identifier; determining if said at least one originator identifier matches an authorization identifier stored in memory of said printer, said authorization identifier corresponding to at least one enable property; and printing said image data file using at least one imaging substance, said imaging substance enabled for said originator.

International Classification:

B41J 1120

US Classification:

400 56

Abstract:

User adjustment of an automatically established gap between a print head and a platen allows adjustment of print head gap relative to a set point by a simple key actuation operation which is preferably conducted during printing operation so that the user can directly observe the result of the adjustment. Storage of user defined adjustment values in non-volatile memory are correlated with measured thicknesses or tolerance ranges thereof and can be recalled after power off/power on cycles and/or after change of paper stocks in the printer. Adjustment limits are imposed to prevent printer damage and user adjustment can be carried out at higher resolution than automatic head gap setting. Graphical and fixed legend displays are preferably provided for confirmation of the adjustment and informing the operator of limits and operating limits and conditions of the gap adjustment.

International Classification:

G03G 1508

US Classification:

399 27

Abstract:

The amount of toner remaining in each toner cartridge (20a-20d) of a printer (1) is estimated by incrementing a count when one pel is detected in each small region of the bit map. The printer senses toner out, after which the scale ascribed to one count is revised to reflect the actual count to toner out. Specifically, the count to toner out becomes the number representative of empty so that one-half of that count is interpreted as half full. The remaining toner in each cartridge is displayed to the operator at a gauge (21).
